The San Diego County Sheriff’s Department on Thursday identified the person they believe to be responsible for stabbing a Cal Fire captain to death in her Ramona home earlier this week.

Authorities asked for public help in their quest to find Yolanda Marodi, suspected of fatally stabbing wife Rebecca Marodi in her Ramona home.

Yolanda Marodi, who is suspected in the slaying of her wife, a Cal Fire captain, pleaded guilty in 2004 to voluntary manslaughter in the fatal stabbing of her then-husband.

Marodi, 49, a captain with the California Department of Forestry and Fire Protection (Cal Fire), was found at her Ramona residence with multiple stab wounds on the night of Feb. 17, after deputies responded to a call for an assault with a deadly weapon, according to a statement from the San Diego County Sheriff’s Office.

A manhunt is on for Yolanda Marodi, the wife of a California fire captain who was stabbed to death earlier this week in her San Diego-area home.

Deputies found Rebecca Marodi with multiple stab wounds, and despite life-saving measures, officials said she was pronounced dead on the scene.

The  County Sheriff’s Office said it has identified Yolanda Marodi, also known as Yolanda Olenjniczak, as a suspect.

Rebecca Marodi was found in her San Diego-area home Monday. A woman has been identified as a suspect in her slaying, but her whereabouts are unknown.

A suspect in the fatal stabbing of a Cal Fire captain in San Diego County was identified by sheriff's officials Thursday, who said the suspected killer remains at large.
